Expandable ambulatory walking device and method of use

Description

FIELD OF THE DISCLOSURE

The present invention generally relates to walking aids, and more particularly, to an expandable ambulatory walking device and method of use.

BACKGROUND

Conventional ambulatory aids provide a user with assistance in getting from one location to another. For example, a conventional wheel chair allows a handicapped user mobility while a user is in a seated position. This may be advantageous for users that may not be able to walk. Some individuals may be mobile without the use of a wheel chair but may require the assistance of a walking device such as a cane or crutch. For example a user may lean on a cane or crutch to maintain balance. However, when a user gets tired, a user must either lean on the cane or crutch until rested or locate a seat to rest. If a seat is not available, a user is left with having to sit on the ground which and may struggle with returning to a standing position. As such, what is needed is a device that may provide a user support when walking and allowing a user to rest when needed without having to locate a seat.

BRIEF DESCRIPTION OF THE DRAWINGS

A more complete understanding of the present embodiments and advantages thereof may be acquired by referring to the following description taken in conjunction with the accompanying drawings, in which like reference numbers indicate like features, and wherein:

FIG. 1 illustrates an expandable ambulatory walking device and expansion mechanism according to one aspect of the present invention; and

FIG. 2 illustrates an expandable ambulatory walking device provided in a collapsed state according to one aspect of the invention.

DETAILED DESCRIPTION

An expandable ambulatory device and method of use are disclosed. According to one aspect, an ambulatory walking device includes an elongated member having a first end and a second end and a rubber contact material coupled to the first end. The device further includes an expandable handle coupled a second end of the elongated member and operable to be provided in a collapsed state providing a handle. The expandable handle is also operable to be provided in an expanded state to provide a seat for the user.

According to another aspect of the invention, an ambulatory walking device includes a first rotational seat portion operable to be rotated approximately ninety (90) degrees to provide a walking state and a seating state. The device further includes a second rotational seat opposing the first rotation seat portion and operable to be rotated approximately ninety (90) degrees in association with the first rotational seat to provide the walking state and the seating state. The device also includes an expansion mechanism including a first hinge coupled to the first rotational seat portion and a second hinge coupled to the second rotational seat portion.

According to a further aspect of the invention, an ambulatory walking device includes an elongated member having a first end portion having a rubber cap and a first hinge operable to be rotated no greater than ninety (90) degrees. The device further includes a second hinge opposing the first and operable to be rotated no greater than ninety (90) degrees. The device further includes a handle bisected along a medial line to provide a seat comprising and a first seat portion formed in a semicircular shape and coupled to the first hinge. The device also includes a second seat portion formed in the semicircular shape and coupled to the second hinge and a stop mechanism operable to limit rotation of the first hinge and the second hinge when rotated approximately ninety (90) degrees.

FIG. 1 illustrates an expandable ambulatory walking device and expansion mechanism according to one aspect of the present invention. An expandable ambulatory device, illustrated generally at 100, includes an elongated member 101 having an end 105 with rubber end tip 103. Expandable ambulatory device 100 further includes a collar 104 and an expandable handle 102 formed to provide a handle for a user to grasp. Expandable handle 102 is bisected into a first portion 106 and a second portion 107. Expandable ambulatory device 100 is illustrated in a collapsed state wherein first portion 106 and second portion 107 are joined to form expandable handle 102. During use, a user may grasp expandable handle 102 of expandable ambulatory device 100 and use as a traditional can or walking aid applying weight as needed to expandable handle 102 to assist with balance.

FIG. 2 illustrates an expandable ambulatory walking device provided in an expanded state according to one aspect of the invention. An expandable ambulatory device, illustrated generally at 200, includes an elongated member 201 coupled between an expandable handle 208 and an end portion 214 having a rubber cap or boot 210. A collar 209 is provided proximal to expandable handle 208 and provides a stop mechanism when expandable handle is expanded to an open or expanded state. Expandable handle 208 further includes a first handle portion 202 having a first curved portion 206. Expandable handle 208 further includes a second handle portion 203 having a second curved portion 207. First curved portion 206 and second curved portion 207 are generally circular and form a semicircle or semi oval shape to allow a user to sit on each curved portion providing support for a user. Other shapes may also be employed.

Expandable handle 208 also includes an expansion mechanism 215 for opening and closing expandable handle 208 based on desired use. Expansion mechanism 215 includes a first hinge 205 coupled to first handle portion 202 and a second hinge 204 coupled to a second handle 203. A cam 211 is coupled to first hinge 205 and second hinge 204 and guides rotation of each hinge when being opened or closed. Cam 211 is coupled to collar 209 and elongated member 201. In one embodiment, first hinge 205 is coupled to cam 211 using a first hinge pin 213 and second hinge 204 is coupled to cam 211 using second hinge pin 212. Other coupling mechanisms may also be used. Each hinge pin extends through cam 211 (not expressly shown) and cam 211 is placed within a cavity or yoke of fist hinge 205 and second hinge 204. Cam 211 may be formed from various types of materials and in one embodiment may include a rubber or plastic material that will allow for easy rotation of each handle while insuring each handle may be rotationally moved between an expanded and collapsed state.

During use a user, a user may grasp a portion of expandable handle 208 when expandable ambulatory device 200 is provided in a collapsed position similar to expandable ambulatory device 100 illustrated in FIG. 1 above. A user may expand or open expandable handle 208 by separating each handle into first handle portion 203 and second handle portion 204 and rotating each until provided in an open state or position to allow a user to sit in a seat when fully expanded. In one embodiment, collar 209 includes a stop such as a lip or ridge (not expressly shown) that inhibits rotation of first handle portion 203 and second handle portion 204 beyond approximately ninety (90) degrees thereby ensuring that stable support of an individual is maintained. In this manner, a user may utilize expandable ambulatory device 200 as a cane (when in a collapsed state) or as a seat (when in an expanded state) as needed.

In other aspects, various types of materials and alterations may be made to provide an ambulatory device that may be used as a walking aid and a seat. For example, expandable handle 208 may take on other various types of shapes and may include various types of materials. For example, first handle and second handle may include a padded material such as foam, final, etc. that may provide a cushion when seated but may also compress when expandable handle 208 is placed in a collapsed position. In another form, expandable handle 208 may include a grip that may allow for a user to maintain a grasp on an expandable handle 208 when being used as a cane. Other variations may also be employed.
